jdbc执行Statement接口的步骤如下:
1)驱动注册程序:
Class.forName(com.mysql.jdbc.Driver);
2)获取连接对象:
Connection conn = DriverManager.getConnection(url,user,password);
3)创建Statement对象:
Statement stsm = conn.createStatement();
4)准备sql语句:(静态的sql语句)
5)执行sql语句:
stsm.executeUpdate(sql);
6)输出:
7)关闭连接:
1 if (stsm != null) { 2 try { 3 stsm.close(); 4 } catch (SQLException e) { 5 // TODO Auto-generated catch block 6 e.printStackTrace(); 7 throw new RuntimeException(e); 8 } 9 } 10 11 if (conn != null) { 12 try { 13 conn.close(); 14 } catch (SQLException e) { 15 // TODO Auto-generated catch block 16 e.printStackTrace(); 17 throw new RuntimeException(e); 18 } 19 }
